Alpine remote control
Crutchfield Customer Review (What's this?)
Not very useful, due to it being an IR remote you had to point at the head unit. An RF remote would have been much more useful. I probably will never use it unless I have someone else driving the van.
Pros: Ok if you are not the one driving.
Cons: An IR remote instead of RF. Hard to use while driving due to having to point it at the radio. It won't work while in it's mount on the dash.
